A TaskDescription's primary color should be opaque

My expo app restarts randomly, I get the following message from logcat:

java.lang.RuntimeException: A TaskDescription’s primary color should be opaque
Using cached or embedded response.
Got cached OkHttp response for https://myapp
Have cached source file for https://myapp
java.lang.ClassNotFoundException: abi28_0_0.com.facebook.soloader.SoLoader
Runtime exception in RNObject when calling method init: java.lang.NullPointerException: Attempt to invoke virtual method ‘java.lang.reflect.Method[] java.lang.Class.getMethods()’ on a null object reference
Could not find listener for key: readyForBundle
java.lang.RuntimeException: A TaskDescription’s primary color should be opaque

on my researches I found that I have to change the primary color under res>values>colors to a non alpha value. But I cant find this file on my project.

On expo project how can I find this style file ? is this the solution ?
tks

Hey there,

Can you describe more about when you hit this error? Is your app detached to ExpoKit or is it just a normal Expo project with only JS? Can you paste the contents of your app.json?
